in my hasty reading of libhtml i was thinking that the tokenization is almost
correct. the only change needed is to not translate \t to 8 spaces. on output,

for rendering, perhaps the solution is to add a flag indicating that the output 
is <pre>-formatted and just memcpy() the text in render.

i was impressed with how little the tokenizing and rendering code was 
special cased, given how ad hoc html is. however, otoh, maybe <pre> should be
handled in a special manner, with the tokenizer just converting character
sets and entities and treating that result as one big Bytes*.

| You are right, there are a lot of things to be improved:
